The aim of this study is to estimate the prevalence of obesity and factors with it Ulsan secondary school girls. A cross-sectional study involving a sample of 485 students aged 12 to 15 years was obtained form secondary schools. Obesity was determined using body mass index(BMI=wt/Ht$^2$). The findings revealed that the average BMI was 19.3, and 4.5% of girls were either overweight and obese(BMI$\geq$25). Subjects were grouped into three categories based on the BMI, sibling obesity, self-consciousness of obesity, eating patterns such as eating snack after dinner and prejudice in food selection, and food frequency score were significantly associated nth BMI, while nutrition knowledge score was not associated with BMI. The fact that several social, environmental and health factors are associated with obesity means that a multisectorial intervention program must be considered in order to decrease the problem of overweight among secondary girls. Such program should include dietary intervention to modify food habits, nutrition education through mass media, introducing information on prevention and control obesity in school curriculum, and allocating sufficient time in the school schedule for exercise activities.

Objectives: The aim of this study was to find out the attitude of Korean women towards IVF surrogacy which is not yet regulated by the law. Methods: We evaluated with a questionnaire, in how far IVF surrogacy was accepted in different groups of Korean women. Total 300 questionnaires were sent out to women who visited our infertility clinic, and to the nurses and office workers of our hospital. Among them, 246 questionnaires were returned, and 211 of them (85.7%) were complete and analyzed. The responders were 58 unmarried women and 153 married women including 60 infertile patients. Results: Only 17 (8.1%) women believed that IVF surrogacy was an acceptable treatment for infertile women without uterus (eg. MRKH or hysterectomized patients), and 125 (59.2%) women chose the adoption. There were no significant differences in response amongst different age group, marital status, or in relation to income level or educational level, or infertility status. A significantly higher level of acceptance was noted only in religious groups, especially in Christians. Most of responders (66.5%) chose unrelated and unknown women as a desirable host, and 28.4% of responders chose the sister or sister-in-law. Conclusions: Overall the different groups were critical towards IVF Surrogacy in Korea, irrespective of the infertile patient group. Despite the established clinical ability to have her own genetic child in women without uterus, this survey reveals that only minority supports the IVF surrogacy. So we need the survey with large, randomized population and then make a regulation about the IVF surrogacy in law.

Allergies are one of the most common chronic diseases during childhood. While the prevalence of allergic disease in children is increasing dramatically, few studies have evaluated the risk and preventive factors related to this health condition, especially in South Korea. The purpose of this case-control study was to evaluate independent determinants of allergic disease, and to examine whether it is associated with growth and other health conditions in childhood. The current study included 209 cases and 311 age and sex-matched controls (fifth and sixth graders) residing in Daegu, South Korea. Environmental data was collected, including child and family histories of allergies, birth information, and reaction to weaning foods during infancy. In addition, current dietary habits (assessed by 2 day-24 hr food records), health conditions, and anthropometric data were obtained through questionnaires and student health check-ups at the school. Based on chi-square tests, cases had a significantly higher prevalence of having a disease at birth, an allergic reaction to weaning foods, frequent hospital visits, and frequent experiences of the common cold and digestive diseases. In addition, significantly more mothers had a higher education in the cases compared to controls. Based on multivariable conditional logistic regression analysis, factors significantly associated with greater odds for having allergies were parental (OR=21.42) and fraternal (OR=14.40) histories of allergies. The anthropometric measures showed that cases tended to be shorter in height and lighter in weight than the controls, but these differences were not statistically significant. These findings may indicate that current nutrient intakes may not be the only critical factor associated with delayed growth delay in the allergic group. A well-planned, large cohort study is warranted to confirm our findings in the future.

The Purpose of this study was to investigate the relationship between congenital muscular torticollis and maternal work activity. This study was conducted with a total of 89 outpatient pregnant women whose child presented congenital muscular torticollis at the Department of Rehabilitation of "C" Hospital in Suwon within the period from 2006 to April 30, 2011. The results were as followings: (1) The mean age at the time of giving birth was 30.09years; the proportion of pregnant women with college education or higher was high; the proportion of first delivery was 82.0%; the most common way of delivery was natural childbirth, followed by Cesarean section and vacuum extraction; the proportion of breech delivery was 20.2%; and in 82.0% of the women, the first child had congenital muscular torticollis. (2) 59.6% of the women had a career; 45.3% had engaged in professional practice or had a related job; 75.5% had worked until the third trimester of their pregnancy; 54.7% had worked for seven hours or more in a seated position; and the mean number of working hours was 8.75 (3) The level of work-related stress was a low 25% or less, and in the subdivisions of work-related stress, only the level of strained relations belonged to the upper 50% or higher. (4) For the correlation between the survey respondents' job stress and job features, stress (full score: 100 points) showed a strong positive correlation with job demand, strained relations, inadequate reward, and workplace culture. Workplace also showed a strong positive correlation with inadequate reward. Mean daily working hours showed a strong positive correlation with mean weekly working hours.

The goal of this study was to examine the economic and cultural factors that influenced the intention of having a second child. In particular, this study intended to examine whether the factors related to the intention of having a child differed by the employment status of married women. The data for this study were drawn from the National Survey on the Trend of Marriage and Birth. This survey was conducted in 2005 by Korean Institute for Health and Social Affairs. The sample consisted of 690 married women who had one child(282 employed and 408 unemployed). The data were analyzed by logistic regression with SAS 9.1 program. The results showed that the employed women's intention of having a second child was affected by the husband's hours of housework, having a own mother(child's grandmother) and the perception of value of child. The employed women's intention of having a second child was affected by the perception of emotional value of child, and the sex of the first child. In sum, there were differences between the employed women and the unemployed women in the variables affecting the intention of having a second child. Perception of value of child was found important for both the employed and the unemployed women. Besides husband's hours of housework, having a mother and the needs for public support about child birth and rearing were found significant for the employed women. For the unemployed women, the costs of child care/education and the sex of the first child were found significant. The findings of this study suggested that different policy interventions be developed to satisfy the needs of the employed women and the unemployed women.

This study was performed to investigate knowledge, attitudes and related behavior on the food hygiene and safety management of school food-service programs among mothers and to find factors affecting their knowledge, attitudes and behavior. A self-administered questionnaire was offered to a random sample of 301 mothers who have children attending elementary schools in one region of Korea. The survey was carried out over a two-month period (April-May,2001). They had lower behavior scores compared to the scores of knowledge and attitudes (p〈0.05). The micro levels of the knowledge, attitudes and behavior scores also showed the same tendency. Logistic regression analysis showed that mothers' education level affected their knowledge and attitudes, while the participating activity in school food-service programs affected their behavior the most frequently. Pearson's correlation analysis confirmed that the knowledge and attitude scores were significantly correlated (r=0.61404, p〈0.001). The results indicate that the knowledge and attitude levels of mothers regarding the food hygiene and safety of school food-service programs were good, however, their behavior levels were not satisfactory. The findings highlight the importance of participating programs in school food-service programs to close gaps between the behavior and knowledge or attitudes of mothers and to improve their behavior levels.

Various international reports have shown strong proof that socioeconomic and sociodemographic variables are correlated with allergic diseases, yet little is known about how these variables affect Korean adolescents. This study was conducted to identify the socioeconomic and sociodemographic risk factors for allergic diseases of Korean adolescents, and to provide information for preventing and managing such conditions. Data from the 2018 Korean Youth Risk Behavior Survey (KYRBS) of 60,040 adolescents was used for this study. An anonymously administered online survey was conducted to collect information on the dependent variables. The independent variables were asthma, allergic rhinitis and atopic dermatitis. Multivariate logistic regression analysis was performed to analyze the correlations between the dependent variables and the independent variables. Low economic status, living with mother, high education level of parents, high school record, obesity, drinking and smoking were the risk factors for asthma. Low economic status, the place of residence, living with mother, high education level of the parents, gender, high school record, obesity, drinking and smoking were the risk factors for allergic rhinitis. Low economic status, living with mother, high education level of parents, genderhigh school record, obesity and drinking were the risk factors for atopic dermatitis. We found that low socioeconomic status and unhealthy behavior were the risk factor for allergic diseases of Korean adolescents. Balanced economic growth in the community and controlling unhealthy behavior can help reduce the prevalence of allergic diseases.

This study was conducted to review the literature and examine the factors related to problem behaviors among students of multicultural families in Korea. A systematic review of the literature was conducted using domestic documents retrieved through July 4, 2018 based on online searches of domestic databases (the Research Information Sharing Service, Korean Studies Information Service System and the National Diet Library). A total of 2,084 studies were searched, and 21 studies were used for analysis. The factors related to problem behaviors were related to individual factors (gender, school record, self-esteem, etc.), family factors (family type, parent support, mothers' enculturation stress, etc.) and environmental factors (friend support, teacher support, social support). The variables measured the problem behaviors among students of multicultural families were school life adjustment (10), psychological, social adjustment or maladjustment (4), and emotional problem behavior (3). Overall, the results indicate that social and policy efforts are needed to improve individual, family, and environmental factors based on more specific and consistent theoretical definitions related to problem behaviors among students of multicultural families in Korea.

This study analyzed 2019 time survey data from the National Statistical Office to examine the childcare behaviors of fathers with preschool children and their determinants, considering types of care and working/nonworking days. The main results of this study are as follows. First, paternal childcare time of nonworking days was three times more than that of working days, and the participation rate was also higher on nonworking days. Second, there was no significant difference in the amount of time spent on primary care and developmental care by fathers, whether from dual- or single-income families. Third, it seems that fathers adjust their participation in childcare between working days and nonworking days in consideration of the mother's time availability. Fourth, the variables related to childcare needs had a significant influence on paternal childcare time on both working and nonworking days. Fathers' developmental care time was not explained by the independent variables entered into the regression analysis. As a result of the study, it is necessary to reduce fathers' working hours and increase family-friendly systems to increase fathers' participation in childrearing. Fathers' perception of parental responsibility must also be changed.
